Cleaning and Preparing Marketing Data for machine learning

Table of Contents

Aim/Objective/Goal

The objective of this case study is to illustrate the process of loading CSV data and preparing it for machine learning using Japio. Users will gain insights into uploading CSV data, utilizing Japio’s features for data preparation and cleaning, and merging two datasets. Through a step-by-step approach, participants will learn to connect diverse data sources, perform necessary transformations, and ready the data for training machine learning models. This case study specifically emphasizes the data cleaning phase, showcasing how Japio facilitates efficient and effective data cleaning. Users can streamline their processes and make informed, data-driven decisions.

				
					#IMPORT DATA

##################################################

#Get marketing data

marketing_df <- read.csv("MarketingReportCoreCSV.csv", fileEncoding="UTF-8-BOM", head = TRUE)

#Lets look at it

View(marketing_df)


				
			

Lets load the data again, this time specifying the separator like so

				
					#Yuck. Needs semicolon seperators.
marketing_df <- read.csv("MarketingReportCoreCSV.csv", sep = ';',  fileEncoding="UTF-8-BOM", head = TRUE)
#Check again
View(marketing_df)


				
			
				
					#K. Now do the same for transactions
orders_df <- read.csv("WebTransactionsCSV.csv", sep = ';', fileEncoding="UTF-8-BOM", head = TRUE)
View(orders_df)


				
			

Cleaning the marketing data

				
					#PROCESS MARKETING DATA
##################################################

#Keep only the columns we care about

desired_columns <-c(1, 4, 7)
marketing_df_clean <- marketing_df[desired_columns]

#Check
View(marketing_df_clean)

#check class is still data frame
class(marketing_df_clean)

#rename columns names
colnames(marketing_df_clean) <- c("date", "channel", "spend")


				
			

Adding, removing and renaming columns ,Finding and replacing strings ,Dealing with different date formatting

				
					#rename "not tracked" to "direct"
marketing_df_clean$channel <- gsub("not tracked","direct",marketing_df_clean$channel)

#rename "unpaid" to "organic"
marketing_df_clean$channel <- gsub("unpaid","organic",marketing_df_clean$channel)

#rename "silverpop" to "email"
marketing_df_clean$channel <- gsub("silverpop","email",marketing_df_clean$channel)
#shorten facebookbusinessadsmanager to just "facebook" as there are no other FB activity in here
marketing_df_clean$channel <- gsub("facebookbusinessadsmanager","facebook",marketing_df_clean$channel)

#check
View(marketing_df_clean)

#set dates to year-month-day using ymd() from lubridate library
library(lubridate)
marketing_df_clean$date <- ymd(marketing_df_clean$date)

#now check the class of this column. must be date
class(marketing_df_clean$date)

				
			

Merging different datasets into one

Japio without coding

Loading Data

Step 1

After logging in to the Japio application at https://app.japio.com  , you will find the “Data Manager” option on the left side of the page . Click on the Data Manager to proceed .

Step 2

If you already have a connection on which you want to transform or visualize the data, click on “My Connections” at the top of the page. You will be able to see your existing connections there.

If you don’t have any existing connections, click on “+NEW CONNECTION” located in the top right corner of the page to create a new connection.

Step 3

https://app.japio.com/data-manager/data-source

After clicking on “+NEW CONNECTION” you will be presented with various data sources from which you can fetch your data into Japio. This will enable you to transform and work with your data within Japio’s platform.

Suppose you want to upload a csv file then hover over the CSV data source, and you will see a “+ connect” button as shown below.

Step 4

After clicking on “+ connect” a dialog box will appear

Step 5

After clicking on the “+connect” button, a dialog box will appear where you will be prompted to provide a name for the connection and upload your CSV file. This step allows you to establish the connection between Japio and the selected data source. By filling in the required fields and clicking the “Connect” button, you will initiate the process of importing the data from the CSV file into Japio. This will enable you to perform further analysis and manipulation of the data within Japio’s platform.

After successfully loading the data, you will be redirected to the data connection page in Japio, specifically to the URL: https://app.japio.com/data-manager/data-connections/data-connection/ connector-id. Here, you will be able to see the connection you loaded with the name you provided during the data connection setup. From this page, you can access and work with the loaded data for further analysis, transformation, visualization, or any other desired operations within Japio.

Access of loaded data
